2009-05-22slirp: Reassign same address to same DHCP clientJan Kiszka
In case a client restarts a DHCP recovery without releasing its old address, reassign the same address to prevent consuming free addresses and moving away from the standard client address. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2009-04-21slirp: Handle DHCP requests for specific IP (Jan Kiszka)aliguori
This adds proper handling of the ciaddr field as well as the "Requested IP Address" option to slirp's DHCP server. If the client requests an invalid or used IP, a NAK reply is sent, if it requests a specific but valid IP, this is now respected. NAK'ing invalid IPs is specifically useful when changing the slirp IP range via '-net user,ip=...' while the client saved its previously used address and tries to reacquire it. Now this will be NAK'ed and the client will start a new discovery round.

Windows Vista drops unicast dhcp replies to its yet-unconfigured address, so use a broadcast address. This behaviour is allowed by the RFC.
